Ford 8.8" 3.55 Ring & Pinion Gear Set

This item qualifies for FREE Shipping in the continental United States!

Change the gearing in your Mustang for better acceleration or top end speed. This 8.8" ring and pinion set is precision-machined from high-strength alloy with a 3.55:1 final drive ratio. This is the same ring and pinion set supplied on Ford Racing Grand-Am GS class FR500C Mustangs. The 3.55 ratio is normally recommended for 1986-95 5.0L Mustangs with 5-speed transmissions, but engine modifications may make a different ratio a better choice for your particular application. Does not include hardware. Speedometer recalibration required. Made in USA.
